Objective To investigate the relationship of sermn C-reactive protein(CRP), IL-18 and insu-lin resistance(IR) in women with polycystic ovary syndrome (PCOS). Methods 36 women with PCOS (study group) and 20 healthy women (control group) were recruited. Serum C RP, IL-18 and sex hormone concentration were tested. Oral glucose tolerance tests (OGTT) and insulin release tests (IR) were conducted in all cases. Body mass index (BMI), fasting glucose to insulin ratio(FGIR), 2-hour glucose to insulin ratio(G120/I120) and homeo-markedly higher T level, LH/FSH ratio , logCRP and IL-18 than control group[(2.77±1.30) nmol/L vs (1.21±0.67) nmol/L, (2.31±0.87) vs (0.58±0.32), (0.16±0.20) vs (-0.47±0.38), (0.21±0.08) μg/L vs vs (22.23±2.68 ) kg/m2, P<0.05] and fasting insulin (I0) concentration [(35.76±24.11) mU/L vs (11.90± 5.32) mU/L, P<0.05)], higher serum glucose (G60=(9.77±2.75) mmol/L vs (7.84±2.02) mmol/L, G120= (7.97+2.07 ) mmol/L vs (6.24±1.80) mmol/L, P<0.05), insulin (I60= (228.38±60.16) mU/L vs (132.46±60.15) mU/L,I120= (172.94±48.39) mU/L vs (90.63±39.79) mU/L,P<0.05 for each) after OGTT and IRT than control group. HOMA-IR increased and FGIR decreased more significantly in study group than controls group (HOMA-IR=(9.59±4.72)vs (3.06±0.82), FGIR=(0.11±0.04) vs (0.23±0.02), HOMA-IR (r=0.5 and 0.37,P<0.05), IL-18 was positively correlatrd with BMI and HOMA-IR (r=0.58 and 0.61, P<0.05). Partial correlation showed that logCRP was positively correlated with HOMA-IR (r=0.46, P< 0.05), but negatively correlated with FGIR and G120/I120(r=-0.54 and -0.48,P<0.05 for all) in test group. Conclusion IR exists in women with PCOS, and their increased serum CRP and IL-18 level shows positive correla-tion with IR,demonstrating that chronic inflammation may participate in the pathogenesis of PCOS, and may have correlation with insulin resistance.

79 cases (180 amputated fingers) underwent gradual distraction through phanlanges. The bone elongation obtained varied from 1 to 3.2 cm, with an average of 2.2 cm. Finger stumps were examined by measurement of 2 point discrimination (2PD) and sensative nerve conduction velocity as well as SO, both before and post lengthening. We confirmed that it was safe to distract the finger stump at a daily rate of 1 mm. Several fingers can be lengthened simultaneously using our device. The adjacent joint was also stretched other than compressed. Therefore, the lateral accessory ligament contraction and joint crush injury were avoided. The long-term length increase was maintained by subperiosteal osteotomy. Gradual finger lengthening is a simple, safe and effective method.

Objective:To investigate the relation of cerebral blood flow(CBF) and memory in patients with cerebral infarction. Methods:The cerebral blood flow of 30 patients with cerebral infarction and 20 healthy controls was measured. The WMS was used for memory function assessment. Results: CBF and memory performance in patients group were lower than those of controls. There was a statistically significant correlation between CBF and memory performances. Conclusion: The decreasing of CBF was an important causal factor to the memory dysfunction in cerebral infarction patients.

BACKGROUND:Previous studies have demonstrated that normal rat liver homogenate supernatant can induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels with partial hepatocyte functions. However, whether fibrotic liver homogenate supernatant can work or how the inducing effect is remains unclear. OBJECTIVE:To investigate the differentiation potential of human umbilical cord mesenchymal stem cels into hepatocytes under the normal liver and fibrotic liver microenvironment in vitro. METHODS:Liver fibrosis was induced in the SD rats by repeated intraperitoneal injections of 3% thioacetamide at a dose of 200 mg/kg body mass, twice a week for 4 weeks, and then fibrotic liver tissues and normal liver tissues were used to prepare liver homogenate supernatants. Passage 3 human umbilical cord mesenchymal stem cels were used and divided into standard control group (cels were cultured in DMEM/F12 with 10% fetal bovine serum), fibrotic liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 50 g/L fibrotic liver homogenate supernatants), normal liver homogenate supernatants group (cels were cultured in DMEM/F12 with 10% fetal bovine serum and 100 g/L normal liver homogenate supernatants). The morphological changes of the cels in each group were recorded under inverted microscope; the protein levels of CK18, AFP, CYP3A4, CYP2E1, CYP2D6 and TPH2 were evaluated using western blot assay. Furthermore, the concentration of albumin in the cels was measured. RESULTS AND CONCLUSION:After a 7-day inducement, the stem cels in liver homogenate supernatants groups lost their fusiform shape and changed into hepatocyte-like cels with the morphous of round shape. Compared with the standard control group, the hepatocyte-like cels in the two liver homogenate supernatants groups exhibited human hepatocyte biomarkers, CK18 and AFP. The standard control group cels could express a little amount of CYP2E1, while cels in the two liver homogenate supernatants groups could express CYP3A4, CYP2E1, CYP2D6, TPH2. Compared with the standard control group, the expression level of CYP2E1 in the two liver homogenate supernatants groups increased significantly (P < 0.01), and however, the relative levels of CYP3A4, CYP2E1, CYP2D6, TPH2 in the two liver homogenate supernatants groups showed no statistical significance (P > 0.05). At the same time, compared with the standard control group, the concentration of albumin in the two liver homogenate supernatants groups markedly increased (P < 0.01), but there was no difference between the two liver homogenate supernatants groups (P > 0.05). Experimental findings demonstrated that both of normal liver tissue and fibrotic liver tissue microenvironments could induce human umbilical cord mesenchymal stem cels to differentiate into hepatocyte-like cels. To achieve the same effect, compared with normal liver tissue, fibrotic liver tissue required lower concentrations, suggesting that fibrotic liver tissue microenvironment may be more conducive to differentiation of umbilical cord mesenchymal stem cels into hepatocytes.
